Thus, in the obscurity of their unlimitedness, bodies can be distinguished only where the “contacts” (“touches”) of amorous or hostile struggles are inscribed on them. This is a paradox of the frontier: created by contacts, the points of differentiation between two bodies are also their common points. Conjunction and disjunction are inseparable in them. Of two bodies in contacts, which one possess the frontiers that distinguishes them? Neither. Does that amount to saying: no one? (Michel de Certeau)
